 for the Year ending 30th June 1915, Maryland Agric. Ex-pt. Sta., 

 College Park, Md., pp. 8-9. [Received 10th July 1917.] 



Leaf-miner pests included : — Phytomyza aquilegiae, eggs of which 

 are deposited in early June on the lower side of the leaves of Aquilegias. 

 Larvae of the first brood remain and pupate on the leaves. Pupae of 

 the second generation hibernate in the ground. A species of Sympiesis 

 was found to be parasitic on this leaf-miner. Control recommended 

 is the eradication of weeds. The boxwood leaf-miner [Monarthropalpus 

 buxi] caused considerable injury in certain districts and is being studied 

 with a view to control. Holly trees were injured by a new leaf-miner. 



Leidigh (A. H.), McNess (G. T.) & Laude (H. H.). Japanese Sugar- 

 cane as a Forage Crop.— Tea^as Agric. Expt. Sta.., College Station, 

 Texas, Bull. no. 195, August 1916, 28 pp., 7 figs. [Received 

 10th July 1917.] 



The insect enemies of Japanese sugar-cane in Texas are not numerous, 

 and the damage caused by them has not as yet been serious. The 

 principal pest is Diatraea saccharalis (cane moth borer), the larvae of 

 which bore into the stalks of the cane, reducing the juices of the plant. 

 Preventive measures recommended are the burning, or, better, the 

 ploughing under of old cane-stalks and leaves from infested fields. 

 Johnson grass and old maize stalks should also be destroyed near cane- 

 fields as the moth borer apparently attacks these crops also. The 

 common chinch bug [Blissus leucoptera], which is very prevalent in 

 Central Texas, does considerable damage to sugar-cane in dry, hot 

 weather.
